DC Remote Control CP0010/XCP0010
DC Control uses a different method to control the base station, which does not provide the functionality
of a tone remote system. Therefore, certain features behave differently or cannot be used on a channel
using dc remote control. Consult with the system supervisor to understand what features are available on
each channel.
Buttons Not Applicable to DC Control
If the selected channel uses dc remote control, some features are not available. These features include
secure operation and MULTI PL. If the operator attempts to activate any of these features, an error beep
is generated.
Frequency Buttons with DC Control
The frequency buttons, F1 , F2 , F3 and F4 in the Frequency window, are used to change the PTT current
for the selected channel. DC channels do not support more than four different transmission currents.
Therefore, multi-frequency is not compatible with dc operation.
Monitor Button with DC Control
The MONITOR button behaves differently on a dc remote control channel than that of a tone remote
control channel. On a dc remote control channel, the monitor function is not latched; and therefore, the
operator must press and hold the
MONITOR button. While the MONITOR button is depressed, the border
of the MONITOR button lights yellow and MONITOR is displayed on the right side of the information
window status line. When the button is released, the border of the MONITOR button returns to its
original color and RECEIVE is displayed on the right side of the information window status line. The
channel and base station are no longer in monitor mode after the release of the
MONITOR button. This
functionality is the same for any channel monitor buttons on a dc channel.
